CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 871,392, dated October 11, 1887.

Serial No. 230.549. (No model.)

To aZZ whom, it may concern:

Be it known that I, \VILLIAM H. TIBBITS, of Crab Orchard, in the county ofJohnson and State of Nebraska, have invented a new and useful Improvementin Car Couplings,of which the following is a specification.

My invention is an improved car-coupling seeking to provide simple constructions whereby to avoid the necessity of raising the link from an inclined position; also, the forming of suchlink to fit for convenientadjustment for coupling with cars of different heights, and to provide in rear of the main coupling devices other coupling devices which may be brought into play on a fracture or other mu-' tilation of the main coupling devices.

Theinvention has for further objects other improvements; and it consists in certain features of construction and novel combinations of parts, as will be described and claimed.

In the drawings, Figure l is a perspective view of the car-coupling. Fig. 2 is a vertical longitudinal section thereof. Fig. 3 is a transverse section of the drawhead through the main pin-opening. Fig. 4 is a transverse section through the rear pin-opening. Fig. 5 is a detail view of the link, and Fig. 6 shows the link intended for use in case of an accident.

The draw-head A may be conxfected with the car in any suitable manner, and has the usual flaring mouth leading into its mortise a. Vertically through this draw-head, near its forward end, I form the pin-openings B, extending through its top and bottom walls, while through its side walls I form pin-openings 0, arranged in a common vertical plane with openings B.

Through the draw-head, considerably in rear of openings B and O, Iform vertical pin-opeir ings D for the pin cl, which in the construction shown may be raised by means of a bail, E, having its cross-bar a connected with the head of said pin D and its side bars, 6, depending on opposite sides of the draw-bar, by means of which bail the pin may be raised when so desired.

The top wall of the mortise a is mortised at F alongside of and in rear of pin-openings B, to receive the pinsupport G. which is pivoted at g, and may rest wholly within the mortise F when it is turned up thereinto. This support is formed with a lateral shoulder, G,

which serves as a seat for the pin when the latter is raised. 1n operation, when the pin is rested on seat G, a link entering the drawhead strikes the support, pushes it back, and releases the pin, which then falls through the link and completes the coupling. The linklifter has a main portion or head, H, formed in U shape, and which fits,when lowered,in a mortise, l1, formed in'the upper side of the bottom wall of the draw-head. At the point of bending a shank, I, is connected with the head, and such shank depends through an opening, 1, in the base-wall of the draw-head, being practically fulcrnmed in such opening. This shank I is connected by a link, i, with a crank, j, on a shaft, J, which shaft is suitably journaled and 'hashand-cranks at its ends, whereby it may be turned. By turning this shaft the shank I may be operated to tilt the lifter to properly elevate the link when the common form of link is used. By preference, however, I employ the special form of link,K, shown in Fig. 5. In this construction one end, k, of the link is made heavier than the other, so that when such heavier end is secured in a draw-head the opposite end will be held up to properly enter a meeting draw-head. I also, by preference, effect this preponderance of weight by making the link thicker at one end than at the other, making it into step form, so that by setting the link at its heavier end on one or the other side it may be set to couple with cars of equal or greater heights.

It will be seen that I form the link with a main pin-slot,L, and a supplemental pin-slot, I, such slots being arranged,preferably,as shown, at right angles to each other. In the construction shown these slots intersect, and such construction is preferred, for the reason that thereby they may be effected in a shorter link. By the described construction, in case the draw-bar becomes damaged as to one or both of holes B, the link can be coupled by passing the pin through the horizontal holes 0 and slot Z. In case the accident should be such as to mutilate the whole front of the draw-head,

when mutilated as to parts of its devices is adapted to operate as to the remainder.

Having thus described my invention, what I claim as new is 1. The herein-described car-coupling link, having one end made thicker than the other, forminga step shape,and having a lateral linkopening formed through such thickened portion, and a vertical link-opening formed approximately at right angles to thelateral linkopening, substantially as and for the purposes specified. I

2. A car-coupling comprising a draw-head provided with alink-mortise and \vit-hhorizontal and verticalpin-openingsleading thereinto, a link having horizontal and vertical pin-open ings, and the pin, substantially as set forth.

3. The combination, in a car-coupling, of the draw-head having opening 1 through and mortise h in the upper side of its bottom wall, and the link-lifter having U-shaped head H and shank I, substantially as set forth.

4. A car-coupling havingits draw-head provided with opening D, combined with the pin (1 and the bail E, having its cross-bar e connected with pin (1 and its side bars depending on opposite sides of the draw-head, substantially as set forth.

5. The draw-head having vertical pin-holes B, horizontal pin-holes O, and socket or mortise F, combined with the pin-support G, pivoted in said mortise and having a seat, G, the coupling-pin, and the link-lifter, substantially as set forth.

6. The improved carcoupling herein de' scribed, consisting of the draw-head having pin-holes B, O, and D,the link-lifter, the main coupling-pin, the pin (1, the pin-support G, the shalt J, having crank j, and the link 'i, all substantially as and for the purposes specified.

7. The combination, with the draw-head, of the link-lifter having shank I, the shaft J, having crankj, and the link i, connecting crank j and shank I, substantially as set forth.

8. The combination, with the draw-head having a pin-opening, B, and a socket or mortise, F, fitted to receive the pin-support, of the pinsupport G, pivoted at 9 within said mortise, and having a seat, G, for the pin, substantially as set forth.

9. In a ear-coupling, a draw-head having pin-openings B and provided considerably in rear thereof with pin openings D, substantially as set forth.
